I'm building a pedalboard for the kemper.
It is based on arduino.
For now it is able to make full use of performance mode, it displays the rig name on the right display. and the effect state on the configured buttons.
What I really miss is the feedback in tuner mode.
Is there any documentation / midi exchanges captures of the kemper communicating with the Uno4Kemper in tuner mode so I can add this.
If you are interested, the code is there: https://github.com/daltona/pedalboard
